The CosmicOne SCT Cooler - or "Cat Cooler" - is a device for ventilating the inside of SCTs, Maks, and other catadioptric telescopes so that they may be brought quickly to ambient temperature. This allows image-ruining tube currents and heat pillars to be minimized in 10-20 minutes instead of the usual 45 minutes to 2 hours. The greater the temperature difference between the place your telescope is stored and the outside evening air, the more quality viewing time you can reclaim with a CosmicOne SCT Cooler. The SCT Cooler has a filtered air intake and other design features which minimize the possibility of dust infiltration and direct the air flow away from the internal optical surfaces.
